HOLLISTON WATER DEPARTMENT is one of 168 community water systems in Massachusetts in the 10,001 to 100,000 people size category, serving 15,139 people from groundwater.
As of August 1, 2026, its federal record holds 5 entries between 1993 and 1998, all of which EPA lists as closed. Nothing has been added since 1998.
All 5 are monitoring and reporting requirements — the category that accounts for about four in five of all violations in EPA's national dataset — rather than findings about the water itself. The record involves volatile organic chemicals and inorganic chemicals.
